Someone (perhaps from SR, I think) did say to me at one point to try ECTs on the amp chassis near the base of tubes, but not on the base itself. They did not say anything about putting them on tubes themselves. I believe that HFTs are not non-conductive, while ECTs are non-conductive. So some care is probably appropriate. I find that tube dampers such as Herbie's HAL-O III dampers do a very good job with tube vibrations and resonance. I use 2 or even 3 of those per tube. I tried ECTs near the tubes, but have found them more effective around digital circuits. Also quite good on cables and electronic circuits.
Alternative application of SR HFT
Last night I had friends over listening to music and checking out the new SR Atmosphere mini. I had extra HFT's laying around and we were trying different placements and one that really stood out was an HFT placed on top of the 5Y3GT rectifier tubes in my PrimaLune prologue 8 CD player and on the 5AR4 rectifier in my EICO 2050 integrated amp. Just sitting on top of the tubes made quite a difference for the better with improved clarity and expanded soundstage.
I'm thinking a high temp adhesive to securely attach the HFT's to the tube would improve things even further but I'm hesitant to go that far and it's quite impressive with them just sitting on top as is. I'm going to try them on the KT88's in my MC275 next to see how that application works out.
If you use a tube component in your system I would highly recommend you give the HFT's a try and see what you think.
Cheers
